Texas Instruments UCD3138A | Demoboard TIDA-00707

Description

TIDA-00707 is a 1-kW, compact (100mmX80mm) power factor converter (PFC) designed for telecom, server, and industrial power supplies. This reference design is a continuous conduction mode boost converter, implemented using a UCD3138A Digital Power Supply controller with all protections built-in. Hardware is designed and tested to pass conducted emissions, surge, and EFT (as per EN55014) requirements. This reference design provides a ready platform of front-end PFC to address various power supplies up to 1 kW, Improves overall system performance lower bus capacitance, lower RMS currents, and front-end protections. It meets stringent current THD and power factor norms and protects from output overcurrent, overvoltage, and undervoltage conditions.

Features
